RT-smart + bsp/qemu-virt64-riscv 无法和 userapps 制作的 rootfs 启动 （TEST 4）

[unicornx]

参考 https://github.com/RT-Thread/rt-thread/issues/9623#issuecomment-2472465702 上的 TEST 4. 请问目前 userapps 主线上做出来的 rootfs 和 prebuild 的 rt-smart 是不是不匹配？

构建命令 history，供参考：

cd userapps
source ./env.sh 
cd apps
xmake f -a riscv64gc
xmake -j$(nproc)
xmake smart-rootfs
xmake smart-image -f fat

另外，应用 #60 后依然不行，控制台输出进入死循环：

挂载 fat.img 后发现文件系统做的有问题，缺少 etc。而同样 rootfs 制作的 ext4.img 挂载后确是好的。

目前定位是默认 image 空间不够导致文件 cp 失败

xmake smart-image -f fat -s 500M 后可以解决该问题。

附件是 xmake smart-image -f fat -v 的 log，其中 “res = 7” 说明镜像空间不够，所以后面的文件都拷不进去了 u2_2024-11-13_18_37_23.log

fat 格式会将所有符号链接全部展开成文件，导致 image 文件体积变大。

同样先不关闭，和 #63 类似，等 #60 merge 后统一测试 pass 再关闭。
